1. You are a geriatric APN, pick 3 physiological systems. Discuss the expected biophysical changes and the associated clinical implications.

There are expected biophysical changes associated with the aging, including changes of the skin and the cardiovascular, pulmonary, renal, neurological, skeletal, and immune systems. Let's look at three of these systems and the associated clinical implications: the cardiovascular; renal: and the neurological and skeletal systems.

1. Cardiovascular system. Cardiovascular changes are significant with aging, and given the prevalence of disease in this system, the majority of elderly individuals today are vulnerable to cardiovascular emergencies. Nearly two thirds of individuals over age 65 years have coronary artery disease (CAD), and although CAD may be asymptomatic, it can influence the heart's ability to withstand a sudden increase in workload. This system with aging, results in vessels that become more sclerosed peripherally and lined with lipid deposits, and the heart valves thicken and become more fibrotic. The left ventricle is required to pump harder against greater resistance, which may result in some enlargement. The baroreceptors are less sensitive to fluctuations in blood pressure, and there is enhanced potential for orthostatic hypotension, particularly in the patient taking diuretics, antihypertensives, and psychotropic medications (Fletcher, 2004).

Clinical consideration must be given when prescribing drugs. For example, generally, the older ...
